The reciprocity fee for Argentina is $160, as of 2015. Argentine law requires that all U.S., Australian and Canadian citizens entering the country with tourist passports pay this fee by credit card at the Provincia Pagos website prior to entering the country.
Once paid travelers must print the receipt and present it to Argentine immigration officials at the point of entry. The fee is valid for multiple entries for 10 years from the date of payment. The traveler must present the receipt upon each entry. Visitors holding diplomatic or official passports must obtain visas in advance, but they do not have to pay the reciprocity fee.
